Sprayed Foam Insulation

I am thinking about insulating under the floor of my three seasons porch. I was talking about this with the guys that were staining my house. One guy said to use spray on foam insulation. I guess it will defy gravity when apply and must work something like that Great Stuff foaming product. I'd never heard of or considered spray on insulation for something like this. Does anybody know anything about it? Sounds like a pretty simple solution.

The porch sits a couple of feet above the ground. I may also want to do something to close it up to block the wind, but that's a different issue for a later time. Just wondering if this spray insulation is a workable solution and where you get it.

I just went to Lowes to check it out and they don't carry it. If they did they would have to also sell the equipment you need to apply it. The guy says you need to get a contractor to do it and he said it's expensive. My painter didn't mention anything like special equipment and didn't even make it sound like it would take much of the stuff to do what I had to do. I'll probably check out the Home Depot and Menards; and do a little Internet research to see what the pros and cons are for my sort of exposed, under porch configuration.

He was probably talking about the fluffy kind of spray insulation for your attic, which is a very common for an attic. This stuff is sprayed on also, but it is a foam type insulation that dries into a solid and adheres like glue.

Re: Sprayed Foam Insulation

A contractor I hired to remodel my bathroom used the spray foam and it worked great. It was a very small area so he purchased some small cannisters of the spray foam from a local insulation dealer. It was two separate bottles that mixed as it sprayed, both bottles were about the size of a 2-liter pop bottle. I doubt you'll find it at Home Depot or Menards but try calling some specialty stores in your area.
